“This is nothing short of a radical breakthrough in [the] British politics of the last 30 years, which have never stepped beyond the so-called Thatcherist neo-liberal consensus of the establishment.”

Corbyn and his official spokesman Seumas Milne also both have a long record of opposition to NATO and Western powers. Last year Milne broke off communications with Westminster journalist after a number of publications named him as briefing that the focus on Russian atrocities in Syria “diverts attention” from atrocities committed by the West.

Russia have also been accused of interfering in the EU referendum.

Labour MP Ben Bradshaw has claimed that hackers attempted to sway the result last June.

“I don’t think we have even begun to wake up to what Russia is doing when it comes to cyber warfare,” Bradshaw told the House of Commons in December.

“Not only their interference, now proven, in the American presidential campaign, probably in our own referendum last year.”

The UK, like other European countries, has strict laws against the foreign funding of British elections.

However, US intelligence agencies were last year instructed to conduct an investigation into the clandestine funding of European political parties by Russia. Moscow has been accused of seeking to boost both far right and far left parties in Europe in an attempt to “divide and rule” the continent. Last year French National Front leader Marine le Pen was forced to deny that her party had been funded by Moscow, after it was revealed it sought a large loan from a Russian bank.
